Installing an Uplink Module in an EX4300 Switch

You can install an uplink module in the front panel of an EX4300 switch. The uplink module in EX4300 switches is a hot-removable and hot-insertable unit (FRU): You can remove and replace it without powering off the switch.

Note: If you have set an uplink module port as a Virtual Chassis port (VCP), removing the uplink module breaks the setting. You must reset the port as a VCP after you replace the module. See Setting an Uplink Port on an EX Series Switch as a Virtual Chassis Port (CLI Procedure).

Before you begin installing an uplink module in the switch:

Ensure that you have the following parts and tools available:

  • Electrostatic discharge (ESD) grounding strap (If a grounding strap is not available, follow the alternative grounding method described in Step 1 of the following procedure.)
  • Phillips (+) screwdriver, number 2

To install an uplink module in the switch (see Figure 52, Figure 53, and Figure 54):

  1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.

    If a grounding strap is not available, hold the uplink module in its antistatic bag in one hand and touch the exposed, bare metal of the switch with the other hand to ground yourself and the component.

  2. If the uplink module slot has a cover panel on it, loosen both captive screws on the faceplate of the uplink module by using your fingers. If you are unable to unscrew the captive screws by using your fingers, use the screwdriver. Hold both the captive screws and gently pull it outward to remove the cover panel, and save it for later use.

    Note: If you are removing an uplink module and installing another uplink module, wait for at least 10 seconds after removing the uplink module before installing the new or the same uplink module. If you do not wait for at least 10 seconds, the interfaces on the uplink module might not come up.

  3. Taking care not to touch module components, pins, leads, or solder connections, remove the uplink module from its bag.

    Caution: Before you slide the uplink module into the slot on the switch chassis, ensure the uplink module is aligned correctly. Misalignment might cause the pins to bend, making the uplink module unusable.

  4. Using both hands, place the module in the empty slot and slide it in gently until it is fully seated.
  5. Tighten both the captive screws by using your fingers or the screwdriver.

Note: If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at . Failure to do so can result in significant delays if you need replacement parts. This note applies if you change the type of power supply or add a new type of uplink module. It does not apply if you replace these components with the same type of component.
